To all whom it may concern:

Be it known that we, HARRY and DoN N. Trroiursoiv, citizens of the United States, and residin at Syracuse, Onondaga County, State of New York, respectively, have invented certain new and useful Improvements in Electric Receptacles, of which the following is a specification.

The object of this invention is to provide a device for quickly and conveniently attaching electric lamp or plug receptacles-to lateral openings for the chain sheet metal supporting members, such as wall fixtures of various kinds, ceiling bands, and sign boards.

- The device is adapted to receive and support standard types 'of sockets, such as keyless and pull sockets, and also to insulate, surround and protect the terminals and other metal parts, while permitting easy access to such parts for wiring purposes.

Our improved attaching means'is simple and economical to manufacture,convenient in use, and it provides a complete lateral insulation for the conducting elements of the receptacle to which it is applied. One

form of theinvention will 'be disclosed in the following description when taken in connection with the accompanying drawings, in which Fig. 1 is a side elevation of the. device as applied to secure a standard type pull switch mechanism to a ceiling band;

Fig. 2 is a disassembled View of the members of Figure 1, the ceiling band being omitted;

Fig. 3 is a disassembled view of the two parts of the attaching device; and Fig. 4 is a top view of the member shown in Figure 1, the ceiling band being omitted.

Although the attaching device is applicable for use with sign boards, wall fixtures, and other similar fixtures, and with various types of sockets, we have illustrated it in connection with a ceiling band and a pull socket for which it is well adapted. When used with a keyless socket, for instance, the guide and chain should be omitted.

In the drawings the numeral 10 indicates the ceiling band, which is preferably of sheet metal, and may have any. ornamental design. This ceiling band has a transverse wall or partition 11 near its lower end with a central circular opening therethrough, the diameter of the circular opening being some- J. Money what greater than that of the threaded shell 12 of the standard pull switch mechanism, which shell extends downwardly therethrough. The lower block or insulating member 13 of the pull switch has a greater diameter than the threaded shell 12, and the lower edge of this member 13 is adapted to seat on an annular flange 14% of a sleeve 14 of insulating material. The lower end of. the insulating sleeve 14, is adapted to bear against the partition 11 of the ceiling band, and the sleeve is of such length that it covers and insulates the metallic members of the pull switch. The top edge of the sleeve is, however, notched at 14 to receive the usual chain guide 13 of the switch. The upper insulating block 13 ofthe switch is adapted to fit in and to electrically close the upper end of the sleeve 14.,

Below the annular flange 11 is a ring 15 also of insulating material which has a knurled lower edge 15 and a threaded: portion 15 in its interior. This ring 15 is adapted-to be secured on to the threaded shell 12 in the application of the device to the ceiling band, and as it is turned it will be apparent that the member 13 will be drawn downwardly toward the partition 11, thereby simultaneously drawing the sleeve 14: against this partition, inasmuch as the member 13 will'seat on theishoulder 14 of the sleeve. The ring 15 has an upwardly extending flange portion 15 which projects through the perforation in the ceiling band and insulates the threaded shell 12 from 'the same; A washer 16 of rubber or similar material may be interposed between the upwardly directed shoulder 15 of the ring and theflange 11. This washer will assist in preventing rattling-of the parts, and unscrewing of the ring due to vibration.

.It will be apparent that the sleeve 14 and the ring 15 may be used to attach various types of standard lamp and plug receptacles to supporting members, and although,

hers, carried by the socket base, is simple in design and easily manufactured and assembled. It will be evident that the invention may be embodied in different forms,

and we do not, therefore, limit ourselves to the exact embodiment shown and described.

. \Vhat is claimed is:

1. The combination with a thin supporting body and an electric lamp socket having an insulating base and a depending externally and internally threaded shell, of a cylindrical insulating sleeve having an open upper end thru which the lamp socket may be introduced, a support for said base on said sleeve, said base being adapted to close the open upper end of said sleeve, and a threaded ring of insulating adapted to screw on said shell to hold said socket in position in said sleeve and to clamp said thin supporting body against said sleeve to support the socket and sleeve.

2. The combination with an electric lamp socket having separated upper and lower insulating blocks and an externally and intcrnally threaded shell depending from the lower block, of a cylindrical insulating sleeve having a support for the lamp socket, the lamp socket being adapted to he arranged in said sleeve with one of said blocks abutting said support and the upper block being adapted to close the upper end of the sleeve, and a threaded ring of insulating material adapted to screw onto said shell to hold the socket in position within the sleeve.

3. The combination with a thin support ing body and an electric lamp socket having separated upper and lower insulating blocks and an externally and internally threaded shell depending from the lower block, of a cylindrical insulating sleeve having an internal support for the lamp socket and a lower end adapted to rest on the supporting body, the lamp socket being adapted to be arranged in said sleeve with one of said blocks abutting said support and the upper block being adapted to close the upper end of the sleeve, and a threaded ring of insulating material adapted to screw onto said shell to hold the socket in position within the sleeve, said ring having its upper end adapted to enter the sleeve and having a shoulder adaptedto cooperate with the lower end of the sleeve to clamp the supporting body.

i. A device for supporting and laterally enclosing and insulating a pull chain switch lamp socket, comprising a cylindrical sleeve of insulating material, the inner surface of which is cylindrical from the upper end inmaterial ward, of sufficient diameter and length to, receive and surround the base of the socket, an

mit the passage of the screw shell but not.

the base of the socket, the inner surface of said sleeve from said shoulder to its end being slightly conical and flaring towards the end, an internally threaded collar of insulating material having such interior diameter as to fit and engage the screw shell of the socket and of such length as to enclose it laterally and having an exterior diameter at its lower portion substantially as great as that of the sleeve and having a slightly conical upper portion of such smaller exterior diameter that it may fit within and telescope the lower slightlyconical interior surface of the sleeve with the upwardly facing shoulder formed by the reduction in diameter adapted to fit the lower end surface of said sleeve.

5. A device for supporting and laterally enclosing and insulating a pull chain switch lamp socket, comprising a cylindrical sleeve of insulating material, the inner surface'of which is cylindrical from the upper end inward, of sntiicient diameter and length to rereive and surround the base of the socket, an interior flange, having a conical upper surface forming a shoulder at the inner end of said cylindrical portion and near the lower end of the sleeve of sufficient diameter to permit the passage of" the screw shell but not the base of the socket, the inner surface of said sleeve from said shoulder to its end being slightly conical flaring towards the end, an internally threaded collar of insulating material having such interior diameter as to fit and engage the screw shell of the socket and of such length as to enclose it laterally and having an exterior diameter at its lower portion substantiallyas great as that of the sleeve and having a slightly conical upper portion of such smaller exterior diameter that it may fit within and telescope the lower slightly conical interior surface of the sleeve with the upwardly facing shoulder formed by the reduction in diameter adapted to fit the lower end surface of said sleeve, said sleeve having a side notch at its upper end to receive the guide for the pull chain.

In testimony whereof we afiix our signatnres.
